| Abstract |
A large part of the world energy requirement is provided from offshore oil and gas fields. The Kashagan site in the Northern Caspian Sea has one of the largest known reserves and marine operations are important for the continuation of activities regarding oil and gas production in area. However, the geographical features of the region make the maritime-related activities difficult. There are different types of marine equipment in operation within the scope of the Kashagan project and one of the most widely used vessel is Multi-Purpose Tugboat / AHT (Anchor Handling Tug). As far as the requirements of the task are concerned, the geographic challenges of the region (especially low water depth) should be taken into consideration when selecting the AHT by the management. In this study, the optimum AHT vessel will be selected to operate in the North Caspian Sea by utilizing MOORA (Ratio and Reference Point approaches) and TOPSIS methods and the concordonce among three methods will be tested by Kendall’s Coefficient of Concordonce (Kendall’s W). |
